Description

Technical Field

[0001] This invention relates to the field of resistor component processing technology, specifically to a processing apparatus for assembling thermal resistor components. Background Technology

[0002] Resistors are one of the most basic passive components in electronic circuits. Their main function is to limit the flow of current, divide voltage, or divide current. Their core parameters are resistance value (unit: ohms Ω), power rating (e.g., 1 / 8W, 1W, etc.), and accuracy class (commonly ±1%, ±5%). According to materials, they can be divided into carbon film, metal film, wire-wound, etc. Metal film resistors have higher accuracy, while wire-wound resistors are suitable for high-power applications. Package forms include axial leads and surface mount (e.g., 0402, 0805 specifications), adapting to different installation requirements. They are widely used in various electronic devices and are key components for stabilizing the circuit's operating state. The selection of a resistor must match the circuit's current, voltage, and ambient temperature requirements.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: See Figures 1-4The present invention provides a technical solution: a processing device for assembling thermal resistor components, comprising four sets of support legs 1, each set of support legs 1 having a fixing plate 2 on its outer surface, and two sets of fixing plates 2 having their inner surfaces fixedly connected to the outer surface of the support legs 1 on the same side. Each set of support legs 1 has a positioning plate 3 fixedly connected to its top, a welding mechanism 4 fixedly connected to the back of the positioning plate 3, and a pressing device 5 fixedly connected to the top of the positioning plate 3. The pressing device 5 includes two sets of pulling plates 504, each set of pulling plates 504 having a downward moving rod rotatably connected to its side away from the support legs 1 via a first rotating shaft. 507. A pressing plate 508 is provided at the bottom of the lowering rod 507. The side of the pressing plate 508 near the lowering rod 507 is fixedly connected to the bottom of the lowering plate. By setting the pressing plate 508, the side of the part can be limited; this ensures that the part will not be displaced during processing, thereby ensuring the stability of the part during processing. The pressing plate 508 is used to restrict the part. The two sets of pulling plates 504 are rotatably connected to the first connecting rod 502 on the side near the support leg 1 through the second rotating shaft. The side of the first connecting rod 502 near the positioning plate 3 is connected to the positioning plate 3. The top of the first connecting rod 502 is fixedly connected to the first connecting rod 502. A movable block 501 is provided on the outer surface of the first connecting rod 502. The side of the movable block 501 near the first connecting rod 502 is slidably connected to the outer surface of the first connecting rod 502. A first spring 503 is fixedly connected to the bottom of the movable block 501. The inner wall of the first spring 503 contacts the outer wall of the first connecting rod 502. The first spring 503 is used to drive the movable block 501 to move. The side of the first spring 503 near the positioning plate 3 is fixedly connected to the top of the positioning plate 3. A second spring 505 is fixedly connected to the top of the lower moving rod 507. The second spring 505 can change the movement angle of the pressing rod; it can ensure that the pressing rod can better fit the accessory with different shapes by adjusting the angle. The side of the second spring 505 near the first connecting rod 502 is fixedly connected to the top of the first connecting rod 502. The side of the moving block 501 near the pressing plate 508 is fixedly connected to the contact plate 506. The inner wall of the contact plate 506 contacts the lower moving rod 507. The pressing device 5 is set in two sets and is symmetrically arranged with the center of the positioning plate 3 as the center. The second spring 505 is used to change the angle of the lower moving rod 507.

[0034] The working principle of this embodiment is as follows: Addressing the issue of displacement during the processing of irregularly shaped RTD (thermal resistance) parts, this mechanism addresses this by placing the part to be processed in the center of the positioning plate 3. The operator then simply rotates the pull plate 504 to initiate the clamping process. This action drives the downward moving rod 507 to rotate at a controllable small angle via a lever mechanism. At this time, the second spring 505 connected to the top of the downward moving rod 507 begins to elastically deform. As the downward moving rod 507 continues to press down, its bottom pushes the counter-pressing plate 508 downwards synchronously. When the pressing plate 508 contacts the surface of the arc-shaped part, the elastic characteristics of the second spring 505 allow the pressing plate 508 to adjust its angle, ensuring a tight fit between the pressing surface and the outer wall of the irregular shape. Simultaneously, the contact plate 506 moves downwards synchronously under gravity, causing the moving block 501 to compress the first spring 503, ensuring stable positioning of the irregularly shaped part and avoiding surface damage caused by rigid clamping, thus completing the work.

[0035] Example 2: Please refer to Figures 5-6 Based on Embodiment 1, the present invention provides a technical solution that further includes a limiting device 6. The limiting device 6 includes an arc-shaped plate 601, which is installed on the top of the positioning plate 3. Four sets of first rotating plates 602 are fixedly connected to both sides of the outer wall of the arc-shaped plate 601. A second rotating plate 603 is rotatably connected to the side of each of the four sets of first rotating plates 602 that is close to each other via a third rotating shaft. The second rotating plate 603 is used for position adjustment. A movable rod 604 is fixedly connected to the side of each of the four sets of second rotating plates 603 that is close to each other. Two sets of rotating plates 605 are rotatably connected to the side of each of the two sets of movable rods 604 that is close to the arc-shaped plate 601 via a fourth rotating shaft. The movable rod 604 is used to fix the position of the rotating plate 605. Circular plates 607 are fixedly connected to the sides of the rotating plates 605 that are close to each other. By setting the circular plates 607, the uneven distribution of gravity can be used to apply downward pressure to both ends of the parts. This ensures that the parts will not shift during processing and guarantees processing stability. Pull ropes 606 are fixedly connected to the top of the two sets of circular plates 607. By setting the pull ropes 606, the moving circular plates 607 can be limited to avoid sudden acceleration and contact with the parts, thereby preventing scratches caused by collision. The sides of the two sets of pull ropes 606 that are close to the movable rod 604 are fixedly connected to the outer wall of the movable rod 604. A rectangular hole 608 is opened on the inner wall of the arc plate 601. The circular plate 607 is used to restrict the parts.

[0036] The working principle of this embodiment is as follows: Addressing the issue of insufficient machining accuracy due to displacement during parts processing, this mechanism addresses this problem. The operator first pulls the second rotating plate 603 upwards. This action, through a linkage mechanism, synchronously drives the movable rod 604 and the rotating plate 605 to rotate together. As the rotating plate 605 rises, the circular plate 607 connected to its top moves vertically upwards. During this process, the pulling rope 606 is simultaneously lifted, further assisting the smooth rise of the circular plate 607. When the part to be processed passes through the inner hole of the circular plate 607, the operator manually pulls one side of the circular plate 607 to initially lift it. As the part fully enters the inner cavity of the circular plate 607, due to gravity, the circular plate 607 automatically tilts. The heavier side naturally sinks and forms contact pressure with the outer wall of the part. This tilting mechanism allows the circular plate 607 to simultaneously fit against both ends of the part, forming a stable clamping and fixing effect, achieving rapid positioning and reliable fixing of the part, thus completing the work.

[0037] Example 3: Please refer to Figures 7-8 Based on Embodiments 1 and 2, the present invention provides a technical solution that further includes a pushing device 7. The pushing device 7 includes an arc-shaped groove 706. An arc-shaped groove 706 is formed on the inner wall of the positioning plate 3. A second connecting rod 701 is fixedly connected to the middle end of the groove wall of the arc-shaped groove 706. A pushing plate 702 is rotatably connected to the outer wall of the second connecting rod 701 through a bearing. By setting the pushing plate 702, the problem of gradual accumulation of welding slag during the falling process after processing can be addressed. The pushing plate 702 can disperse the accumulated welding slag to all sides by swinging left and right, thereby avoiding welding slag accumulation. Slag accumulation interferes with subsequent processes. Two sets of first mounting rods 704 are fixedly connected to the side of the push plate 702 away from the welding machine mechanism. The push plate 702 is used to push the welding slag to move. Elastic ropes 703 are fixedly connected to the outer walls of the two sets of first mounting rods 704. Second mounting rods 705 are fixedly connected to the side of the two sets of elastic ropes 703 away from the first mounting rods 704. The side of the two sets of second mounting rods 705 near the positioning plate 3 is fixedly connected to the inner wall of the positioning plate 3. The elastic ropes 703 are used to pull the push plate 702 to reset and move.

[0038] The working principle of this embodiment is as follows: During the processing of the parts, the welding slag will move downwards under the action of gravity. As processing continues, the downward-moving welding slag will gradually accumulate in the mechanism. If it is not cleared in time, this accumulation will affect the normal operation of the mechanism. The mechanism will handle this. When the welding slag moves downwards to the position of the arc-shaped hole, due to the arc-shaped transition design on one side of the inner wall of the arc-shaped hole, the welding slag falling into it will naturally disperse and slide to both sides of the push plate 702 and begin to accumulate under the combined action of gravity and arc-shaped guidance. When the amount of welding slag accumulated on one side reaches a critical value, the lateral thrust generated by the accumulation will push the push plate 702 to move to the other side. During the movement of the push plate 702, the elastic rope 703 on its side is stretched. Under the combined action of the deformation energy storage of the elastic rope 703 and the pushing force, the originally accumulated welding slag is pushed to all sides, realizing the dispersion and guidance of welding slag. When the push plate 702 completes the unidirectional displacement, the stretched elastic rope 703 will generate the elastic force to restore its original shape. Under the action of this elastic force, the push plate 702 begins to reset, and at the same time drives the welding slag on the other side to move in the opposite direction. Through the reciprocating motion of the push plate 702 and the elastic recovery mechanism of the elastic rope 703, the welding slag forms a dynamic circulation and guidance in the mechanism, effectively avoiding the impact of local accumulation on the operation of the mechanism, thereby completing the work.
